Backing against the 57North ID LDAP database for SSH public keys, git.57north.org.uk provides simple git repository hosting. At present, all 57North ID holders have access to this - once HackHub is integrated with 57North ID, this will be restricted to members.
Public repos are viewable via cgit at https://git.57north.org.uk. This service is hosted on Garioch.
